Stretch is seen glaring at the camera while pulling
his jumper up and standing in another sexual pose.

The footage is the latest in a series of evidence including a chilling series of ‘selfies’ taken just moments before the woman and her accomplices went on the run.

Joanna Dennehy, 31, has admitted stabbing three men in the heart and dumping their bodies in ditches.

Victims her former lover Kevin Lee, 48, his friend Lukasz Slaboszewski, 31, and his housemate John Chapman, 56, were found left by fields outside Peterborough in March and April last year.

Despite murdering three Dennehy remained ‘unsatisfied’ and fled to Hereford in search of more victims, the Crown says.

self-harming.

She cruised the city and selected two other men at random, stabbing Robin Bereza, 64, and John Rogers, 56, who survived the cold-blooded attacks.

Alleged conspirators Gary Stretch, 47, and Leslie Layton, 37, who are now on trial, deny helping to cover up the “terrible truth” of the murders.

Pictures of Dennehy and Stretch were shown to Cambridge Crown Court as Mark Lloyd, an associate of Gary Stretch, and Georgina Page, a friend Dennehy’s gave evidence.

The shocking images include one of Dennehy jovially sticking her tongue out as she brandishes a jagged knife with handcuffs attached to her trousers.

And in another two pictures the defendants are seen gesturing to the lens.

A final image shows the pair casually leaning on a fence just minutes before Dennehy tried to stab another two men to death.

The court heard that the murderer leapt out of a car she had been travelling in looking for victims and stabbed dog walker Mr Bereza ‘like a scene from Pyscho’.

Stretch looked on without emotion and Dennehy returned to the car and kissed him on the cheek “as if to say thanks”, the court heard.

A witness told how the second attack was a “brutal re-run” of the stabbing just moments earlier.

Dennehy then brought the victim’s whippet back to the car and sat with it on her lap and tried to stroke it as it physically shook on her lap.

Dennehy treated 7ft 3in Stretch “like a puppy” and the giant would be dead if the killer hadn’t needed him to drive her around, jurors heard.

Ms Page, a grandmother, told the court how she and Dennehy became friends while serving jail sentences together.

She said she next saw her former cell mate when she and Stretch turned up on her doorstep in King’s Lynn following the murders.

She said: “When I was inside with her she wasn’t a murderer or nothing. At first I didn’t believe her.

“I was very shocked. I was scared, I didn’t know what to do.”

The court also heard that during the pair’s stay at Ms Page’s house Dennehy was jumping around in delight at seeing her face on the news.

Ms Page said the killer downed whisky and ate a ham sandwich while bragging about her violent acts.

She said: “I was terrified. Stretch turned round and said that if anyone grassed on them he would get his dad to sort them out.

“Joanna was talking about something and saying ‘you know we’re going to get caught and sent to jail for a long time’.”

She also said Dennehy told her that she “wanted to be caught like Bonnie and Clyde.”

And when she asked her why she had killed Dennehy responded: “They shouldn’t have flirted with me.”

A picture of the knife believed to be used in all five attacks was also shown to court and described as a nine-inch fold knife.

Mr Lloyd said he saw the same knife in Dennehy’s hands at a flat in Hereford occupied by his friend Moby.

It was there that Dennehy took pictures of herself and Stretch as they prepared to drive round the city in a bid to kill again.

Mr Lloyd told the jury that the blade “was as black as the handle” because of all the congealed blood and that it “smelt like copper”.

He said Dennehy than told him: “I’ve killed three people, Gary’s helped dispose of them and I want to do some more.

“You’ve had your fun Gary, I want my fun.”

Mr Lloyd also revealed that Dennehy flirted with him and “caressed” his neck and backside.

He told the court she said: “I wish I could have met you last year, you’re my type of guy.”

He said that Stretch “was not liking it one bit” before the three of them got into the green Vauxhall Astra that the killer had travelled in from Peterborough.

Mr Lloyd then said he tried to call the police while Stretch drove around Hereford looking for victims for Dennehy.

But he failed to do so and told a court that “Gary was the taxi driver, she went around killing people”.

Dennehy, of Orton Goldhay, Peterborough, pleaded guilty to the three murders and two attempted murders at the Old Bailey in November.

She also admitted preventing the lawful and decent burial of all three victims and is in custody awaiting sentencing.

Her victims were her lover Kevin Lee, 48, his friend Lukasz Slaboszewski, 31, and housemate John Chapman, 56.

All three men were stabbed and their bodies dumped in fields outside Peterborough.

Stretch, of Orton Goldhay, real name Gary Richards, denies three counts of preventing the lawful and decent burial of a body and two counts of attempted murder.

Leslie Layton, 37, of Orton Goldhay, denies two counts of preventing the lawful and decent burial of a body and one count of perverting the course of justice.

A third man Robert Moore, 56, of Peterborough, has admitted assisting an offender and is awaiting sentence.
